Abstract

Ti:Al₂O₃ optical windows are advanced engineered materials combining the superior hardness of alumina (Mohs 9) with titanium-enhanced optical performance. Synthesized via high-temperature melting and precision doping, these windows exhibit exceptional transmittance (≥92% in visible spectrum) and UV-induced blue fluorescence (450nm peak). Key advantages include extreme durability (Vickers hardness 2300-2800 MPa), high-temperature resistance (up to 1800°C), and corrosion/radiation stability (pH 1-13, γ-ray attenuation <0.5%). Designed for industrial and scientific applications, they optimize performance in semiconductor lithography (sub-3nm alignment), LiDAR systems (-40°C–85°C operation), and high-power lasers (1064nm, 10kW/cm²). Cost-effective and customizable, Ti:Al₂O₃ windows redefine reliability for cutting-edge optical systems.
